Also the "10,000" hour rule (which has obviously been debunked) isn't
really about 10,000 hours of focused practice on the task alone. Focused work and previous experience in other domains transfers into the activity/goal you chase.
Being a Data Scientist gave me a huge leg up about understanding data structures and statistical analysis, huge in my field.
Formerly a software developer, I was able to install, configure, and hack together a workable WooCommerce/WordPress PHP/MySQL CMS that generated content and still is our main shop, selling millions of dollars of merchandise per year.
I used to work retail and retail management when I was young and putting myself through high school and college. Lessons about stocking, shipping, marketing, sales, logistics - all transferred into my online retail business.
None transfer perfectly, but all make an impact. True, I knew nothing about "sports science" at the outset. But I had a big leg up from my limited college education and my extensive work history. That cut the "10,000" hours down significantly.
